These LED bulbs install into grow light fixtures and provide light for plant growth. LEDs use less energy than other lighting technologies and run cool so lights can be placed within inches of plants without causing wilt or burn. Standard bulbs have a screw-in base to fit sockets on clamp-on and string grow lights. Linear bulbs have a pin-style base and tube shape to fit linear bay and strip grow lights. Grow lights emit light in color spectrums that optimize seedling growth, stem and leaf growth, or budding and flowering to grow plants indoors. They are rated for wet locations to withstand high humidity and resist water sprays. Grow lights are used in greenhouses, hydroponic gardening, vertical farming, farm-to-table and urban farming, agricultural research, and other indoor growth applications.
